Latest Patents
One of Marki Volker's latest patents is titled "System, method, and computer program product for progressive query processing." This invention aims to improve query processing by validating the statistics and assumptions used during query compilation as the query executes. When necessary, it progressively re-optimizes the query mid-execution based on insights gained during its partial execution. The invention introduces CHECK operators in a query execution plan to validate the optimizer's cardinality estimates against actual cardinalities. If errors exceed a certain threshold, re-optimization is triggered, allowing the optimizer to determine if the old plan remains optimal and whether to reuse previously computed results. This invention is capable of handling arbitrary SQL queries, including those with sub-queries, updates, trigger checking, and view maintenance operations. It also effectively manages concurrent update transactions without compromising consistency and isolation, as locking information is tied to the record ID.
